Kismalm kan sees i to knauser som stikker opp av steinura,en ca.50 m ovenfor vegen og den øvre enda ca.50 m lengre oppe. Forekomsten er helt ubetydelig og forekommer som smale årer og ganger i en finkornig og massiv gneis. Skredali kisforekomst skulle i følge en tidligere befaringsrapport i malmregisteret (se over) ligge 50-100m sør for riksvei 45 ved søndre utløp av veitunnelen ved Giljajuvet. Et område med diameter på 200m rundt den tidligere koordinatfestete lokalitet ble gjennomtrålet uten at forekomsten ble funnet. Det ble søkt på begge sider av en bergnabbe som stikker ut i ura ned mot veien og til en høyde av 360 m.o.h. Forekomsten ligger sannsynligvis lengre vest enn det befarte området.
